Ping An said the investment is a financial one based on the bank's strong performance and track record of paying dividends.

The investment represents a reversal in the historical relationship between the two financial firms. HSBC in 2012 sold its $9.38 billion (£7.1 billion) stake in Ping An to a conglomerate controlled by Thailand's then-richest man Dhanin Chearavanont.

Ping An said it build up its 5 percent stake in HSBC by buying its Hong Kong-listed shares via the Stock Connect program which allows mainland Chinese companies to buy Hong Kong shares, and vice versa.
